Hippocampal sulcus remnant cysts, also known as hippocampal cavities, are remnants of incomplete involution of the embryonic hippocampal fissure and are an incidental finding.

Epidemiology

They are seen in ~25% (range 10-40%) of the adult population .

Radiographic features

MRI

They consist of small (1-2 mm) cystic spaces that follow CSF on all sequences. They are located between the dentate gyrus and the cornu ammonis, at the lateral aspect of the hippocampal region, near the apex of the hippocampal fold .
